Extending rearwardly from the' p teeth 9, and integral' therewith, are'l inclined .portions 11 consisting of a continuatieii-"of the teeth extending rearwardly and? joinin a horizontal table 12. 'llifco-tto'n picker' from the boils asses from the piclerteeth 9 to the, inclined) portions 11, 4and from the latter .to the horizontal table 12. The effective lengtlrof the teeth-9 may be regulated by a roller .13 which is adjustably mounted there-below- The adjustment of this roller may be rearward or forward and is accomplished throughadji-isting screwsv 14 which engage .opposite sides of the bearings 15. for the Journals of said roller; said bearings heilig Supported upon the side frames of the When 'the' cottonv is torn from the bolls and advanced to the inclined portions ll'of the picker teeth, it is subjected to an upward air draft of a sufficient strength only to` blow any dust or foreign substance away from said cotton. 4 Thls uiward au' blast is obtained by means 'of a lower 16 from which the air is directed through an extended casing 17'beloW the inclined portion of the icker teeth and is there delivered 'upwarfv 1y to the picked cotton.' The -ered cottonis'remeved te the portion of the tion of'mevement of the .carrier is indicated shafts of the chain wheels 28 and 30v have gear. vIt will thus far be seen that all the power necessaryto o erate the blowers and the picker teeth te move said cotton onto iorizental table 12, and thence te the endless belt carrier.19 to be again referred 'I he down draft of air is maintained by means of a blower 20 which discharges the air through a blower pipe `2'1 above the inclned portion 11 of the picker teetln'aand to the rearward of the extended casing 17. The blower 20 is operated from the main axle 2 by meansof a belt er chain 22 and suitable wheels,` and is placed o'n the side of 4the machine ep esito that upon which the blower 16 is located. y, I

The eonveyer by means of which the sevmachine for its nal removal, consists of an endless belt 19 upon which is arranged a series of teeth 23 extending across said belt in rows.' These teeth 23 are curved in a manner to engage the lcotton delivered thereto from the table 12 and to carry said cotton forwardly beneath said table and to the receptacle 24 in the front end of the vcasing 25; the casing 25 is of sheet metal and ineloses the entire machine except at such points where it is necessary to enable access to be hadto the front receptacle 24 for the removal of-the cotton. The direcby the arrows in Fig. 3, and themevement is imparted to said carrier from the main axle 2 which has thereon a chain wheel 26` Connected with a chain wheel 27 en the axle ofthe front chain wheel 28 around which the forwardend of the carrier asses. 'I he connection between the whee s 26 and 27 censists of a chain 29. The rearward end of the carrier passes around a chain wheel 30. rI'he bearings in the side frames 4 of the running the'carrier, is derive from the main) axle of the machine. In the front of the 'inachine near the carrier, there is a rotating brush 31, the shaft 32V of which is journaled in bearings on the side. frames 4 and is driven from the main axle 2 by means ef a chain 33 and suitable wheels. rIhe-purpeser ofthis rotating' brush is teclear the teeth 23 of any accumulations that may be disposed to cling thereto.

In order that the picked'cetten may not advance too far rearwardly upon the carrier 19 when delivered thereto from the table 12, I rovide a series'of 011e or more rotating cylinders 34 with suitable projections thereon which rotate above the carrier in a manner to prevent the cotton from passing thereunder rearwardly upon the carrier. 'Ihese rollers 34 have their shafts mounted in suitV- able bearings 35 on the upper portions of the at the lower end of the inclined portion of y ward wheel 30 of the carrier subjecte side frames 4, and are driven from the rearby means of a cross chain 36 which asses around a suitable wheel on one of saidP roller shafts 34, and a further chain 37 which transmits motion to the remaining rollers 34.

.As the machine is drawn ferward'by the draft animals', the cotton is strip )ed from the bells. The rotating roller 13 below the teeth preventsy the stalks from clogging up the teeth. The roller rotating under the teeth engages the retreating stalks andprevents them being Aforced back into the narrow space where the teeth are joined. The stalks are drawn through the teeth against the roller, have the effect of rotating the roller and the latter will prevent the clogging of the teeth. The teeth are seV spaced that the stalks or bells are allowed to enter them and to pass through said teeth while the cotton is stripped, and delivered to the rearward or inclined )o1-tien 11 ef said teeth where it is d te the upward current of air. As the cotton accumulates upon said irclined portion of the teeth, the down draft of air deivered thereto, moves said cotton onto the table 12 and thence te the carrier which delivers it to the receptacle 24 in the lower forward portion of the casing 2'5.

I claim:

l. In a .cotton picker, the combination with a series of picker teethhaving portions extending rearwardly a'nd downwardly, means for preventing the stalks of cotton from clogging said pieker teeth, means for delivering a current of air to the severed cotton after it passes te the rearwardly inclined portions of the picker teeth, and means for delivering a current of-'air te the cotton to move it rear wardly, and an endless belt carrier with suitable teeth thereon, a receptacle to which said carrier delivers the cotton, and from which it is iinally moved.

2.' In a cotton picker, a. table, a series ef picker teeth having graduated spaces between them, said picker teeth having pertions extending rearwardly and downwardly and joining the table, means for delivering upward and downward currents of air te the cotton after it passes te the rearwardly inclined portions of the picker teeth, and an endless belt carrier having suitable teeth thereon by which the cotton is removed to a part of the machine for its [in al removal from the machine.

3. Ina cotton picker, a series of picker teeth terminating rearwardly and downwardly, a horizontal table joining the rearward inclined portions of said teeth, an adjustable roller mounted below the teeth te prevent the stalks ef cotton from clogging said teeth, and an endless belt carrier having curved teeth thereon which engage the severed cetten as it is delivered thereto from the table.
